The power-efficient coherent interface technology will enable Telia Carrier to double the capacity and reduce latency on its DWDM infrastructure, which is based on the Coriant’s hiT 7300 multi-haul transport platform.

The first deployment of Coriant CloudWave Optics in Telia Carrier’s network will include a 400G-enabled fibre route between the cities Copenhagen, Denmark and Frankfurt, Germany.

Via the software programmable modulation capabilities, Coriant Cloudwave Optics will also enable Telia Carrier to maximise reach and performance throughout its wider network, including the challenging fibre routes such as subsea long-haul transmission to London, a major Internet hub in the region.

‘As our customers in Europe experience increased demand for capacity to support their business-critical applications, we are committed to investing in best-in-class innovation to stay at the forefront of service excellence,’ said Mattias Fridström, chief technology officer, Telia Carrier. ‘The Coriant solution enables us to significantly improve utilisation of our existing DWDM infrastructure and rapidly provision new services to meet our customers’ dynamic connectivity requirements.’

BT has made an offer to the UK government to voluntarily provide high-speed broadband to 99 per cent all homes and businesses across the country within five years, which would largely be delivered by Openreach.

The government said it received the offer after it committed to introduce a Universal Service Obligation (USO) through regulation to give every home and business in the UK the right to request a high-speed connection of at least 10Mb/s.
